Robotic Mitral Valve Repair: Contemporary Evidence, Clinical Outcomes, and Implementation Considerations

Robotic mitral valve surgery (RMVS) is increasingly used as a minimally invasive approach for mitral intervention in specialist centres. This narrative review summarizes contemporary evidence from matched observational studies, national database analyses, and meta-analyses comparing RMVS with sternotomy and mini-thoracotomy approaches, with emphasis on perioperative outcomes, repair quality, durability, learning curves, program implementation, and cost. In experienced programmes, RMVS is associated with high repair rates, low mortality and morbidity, with shorter intensive care unit and hospital stays and faster postoperative recovery than sternotomy-based pathways. Operative, cardiopulmonary bypass, and aortic cross-clamp times are generally longer, particularly during early adoption, but improve with cumulative experience and workflow standardization. Economic findings are less consistent, with reported costs ranging from equivalent to higher than conventional approaches depending on case volume, analytic perspective, and treatment of capital expenditure. Successful implementation depends on careful patient selection, multidisciplinary team training, dedicated infrastructure, and prospective quality oversight. Important limitations of the current evidence base include the predominance of observational data, centre-volume effects and whether this technology is applicable in low volume programs, robust health-economic evaluation in resource-constrained systems and limited direct comparison with totally endoscopic non-robotic mitral surgery. Overall, RMVS is a very safe and effective approach for mitral intervention when delivered within an experienced, protocol-driven programme.
